 But it's interesting, John, I didn't realize this, 15% of a Boeing 787 Dreamliner is actually titanium. And the real technicalities of this, they use grade 3 and grade 5 titanium, something called TC4. But without going into too much detail there, pretty serious when you talk about issues like this that have what? Claiming to have some holes in the corrupted titanium. So they supposedly have removed titanium.
